1.) Fleur, Las Vegas
Widely thought to be the most expensive burger in the world, this $5,000 concoction consists of Kobe beef, foie gras and lots of truffles. The price tag also includes a rare bottle of Petrus and diners get to keep the glasses too.
2.) Smokey Robinson
Made from patty, cheese, tomato, lettuce, caramelised onions, bacon, ketchup and smokey P&B mayo in a brioche bun.
3.)
In-N-Out burger, California
Popular in LA, In-N-Out focuses on fresh ingredients and even offers a “protein style” burger, which uses lettuce leaves instead of a bun. No surprise Angelenos love it - but whether their claim that it's better than anything offered on the East Coast is open to debate.
